EMBOSSED-PRINTING MACHINE,

Application filed June 23, 1925. "Serial No. 39,084.

This invention relates to machines for producing printin to simulateengraving or embossing, and t e said invention has for an object theprovision of novel means whereby multicolor printing may be done; thesaid printing while in a moist state being coated with a powder orgranular material which is afterwards subjected to heat after theprocess well known in the art in which embossing machines are employed.

It is a further object of this invention-to produce a printin device ofthe character indicated in association with a supply of material to beprinted, and in which the material is drawn through the printingapparatus in the form of a web; and the said device includes means forimparting motion to the web in a step by step travel, so timed as topermit the printing mechanism to operate successively on the web as itis passed through the printing machine so that multicolored plrintingcan be done when desired, althoug of course, the same features may beemployed where one color ink is being distributed or used.

Furthermore, it is an object of this invention to provide a coatingmeans through which the web is drawn after it is printed, whereby theprinted surface is provided with a deposit of any of the well known orspecial coatings that are melted or partially melted when subjected toheat, for the purpose of producing the raised or embossed" effect; and

it is furthermore an object to associate with.

the last mentioned means an agitator or tapping device which will beoperative to dislodge excess deposits of the aforesald material from theweb prior to the time it is subjected to heat, as will presently appear.

It is a still further object of the invention to provide a suitableguide and drawing rollers which pull the web through the printingapparatus and the coating applying means in order that the said web maybe delivered to a cutter which will sever the web into appropriatelengths to produce cards of different sizes or sheets of material thathave been treated.

It is a still further object of this invention to provide novel meansfor operating the cutter in time with the drawing rolls and the printingmechanism.

It is a further object of this invention to produce a conveyer and,furnace or oven effective to j ct the eie e a d t e t d. and

intense heat.

heat the cut sections of web and the de-' posits thereon so that thesame will be hardened, as 15 done in machines of the charactermentioned.

It is furthermore an object of this inventionto produce a heater oroven, through whlch a conveyer travels for carrying the printed and cutmaterial, and in order that the deposit may be properly baked without inury to the card, or the cardboard (the same to be hereinafter referredto as cards, the sald term being understood to mean any stock in thenature of cardboard, aper or the like bearing the deposits), it Has beenfound in practice that it is desirable to subect the said cards to theaction of comparatively intense heat intermittently and to maintain thetemperature of the cards in a heated state between the zones of the moreBy the arrangement just stated, the heat is not sufiiciently great toimpalr the cards or scorch them, while at the same time, the depositsareproperly heated so that they set and remain hard.

It is astill further object of this inventron to produce novel means forregulating the temperature of the oven by the employment of sectionalheaters which may be controlled in sections to produce the desiredtemperatures, and the said heating device, which is in the nature ofelectrical resistance coils, may be expeditiously and inexpensivelyrepaired, since each resistance elementis of short length separatelyinstalled.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, ref-- erence will be had to theaccompanying drawings forming part of this application wherein likecharacters denote corresponding parts in the several views, and in whichFigure 1 illustrates a view in elevation showing a printing deviceassociated with a coating device;

n these drawings, 15 enotes a printing press having multicolor distrbuting rolls 16, 17, 18 and 19 that operate in conventional manner withrespect to the type, and other parts of a printing press wh1ch need not,it is thought, be described 1n detall.

A bracket 20 rotatably supports a roll 21 of material which is to be cutinto appropriate lengths for producing cards after the web 22 has passed,through'the printing press and through the coating means 23.

The coating device, in the present embodiment of the invention,comprises a box-hke structure rectangular in plan, whose end wall 27 isrotatably supported at one side of the 24 terminates above the bottom 25to produce a slot or opening 26, through whlch the web is drawn, as willpresently appear. A roller device slightly above the bottom in orderthat the printed web may be drawn through the coating means close to thebottom thereof and under the coating material. The web is then guidedthrough a slot 29 in a guide 30 to the drawing rolls 31 and 32 between.which the web travels and from which the web is projected over thestationary knife 33. In order that excess deposits may be removed fromthe web, a tapper orknocker. 34 is oscillatable in the path of travel ofthe web and it strikes the web intermittently to jar or vibrate it sothat excess deposits are removed and descend. into the receptaclethrough which the web has traveled.

' .The tapper, in the present embodiment of the invention, has a roundedinner end which strikes the web and a tail piece 35 which extendsoutwardly into the path of rotation of the shoulders 36 of the shaft 37.L

The roll 31 has peripheral flanges at its ends in order that the flangeswill engage the cards at the edges and straddle the printed surfaces ofthe cards, whereas the periphery of the roll 32 is plane and supportsthe card throughout its surface.

The rolls 31 and 32, as well as the shaft 37, are geared together by atrain 38 in order that they will operate in unison, the roll 32 beingpositively driven through the pinion 39 and gear wheel 40, which gearwheel 40 is secured on a shaft 41 journaled on a post 42 in any suitablemanner. The gear wheel 40 is engaged by a dog 43 that is pivoted on anarm 44' carried by a sleeve 45 that is rotatable on a shaft 46, and theaction of the dog is controlled by a segmental shield 47 having a hub 48adjustable on the shaft on gage a tooth of the wheel 40 and impartrotary motion to the said wheel. If the shield 47 is positioned torelease the dog to engage the wheel early in its movement, the degree ofrotation of the wheel 40' will be greater than that when the'shield isset to prevent the dog from engaging the wheel 40 so early in itsmovement, and it is by this arrangement that the degree of movementimparted to the web at each operation of the drawing and cuttingmechanism and the size '.of the card severed from the web is determined,as it will control the length of the feed of the drawing rolls. The hub48 may be secured to the shaft at different positions of adjustment byany suitable means such as a set screw, as those skilled in the art willunderstand. 'L

As has been stated, the web is drawn in a step by step motion overtheknife 33 and a. movable knife 48 operates in conjunction with thestationary knife for cutting the cards. The knife is oscillatable on theshaft 46 in conjunctlon with a frame which is also oscillatable, and thesaid frame, in the present embodiment of the invention, consists of arms49 and 50 which are conneeted'together by a rod 51, and the knife '481s-also connected to the said rod 51. The knife 48 and the arm 49 haveprojecting trunnions 52 constituting wrist pins on which pitmans orconnecting rods 53 operate. The arm 49 has a hub 54 rotatable on theshaft 46 and the arm 50 has the sleeve or hub 45 on its end, the saidsleeve 45 and its function having been described, and the knife iscarried into an operative relation to the knife 3321s the frameoscillates.

A power shaft 56 is provided with a drive wheel 57 that may have powertransmitted to it in any appropriate way, as by a belt, and the saidshaft 56 has a pinion 57 secured to it which meshes with a gear wheel 58on the shaft 59. The shafts 56 and 59 are ro- I located a suitabledistance rearwardly of the printing mechanism and parts associated withit. The gear wheel 58 has a wrist pin 62 to which an end of a pitman 53is connected, the wrist pin, of course, being eccentric to the shaft.The shaft 59 also has a wheel 63 on the end opposite the wheel '58 andit has a wrist pin 64 to which a pitman 53' is connected in order thatpower may be applied to both ends of the frame for imparting oscillatorymotion to the said frame.

From the foregoing description and by reference to the drawing, it wi 1be apparent that a web of material to be treated or printed is drawnfrom the roll 21 through the printing press or mechanism and threadedthrough the coatin means under the roller-27 and through t e slot of theguide 30, the relation of parts being such that the web will pass insuch juxtaposition tothe tapper as to be intermittently struck by thetapper as the tapper oscillates, it being understood that the tapper isoscillated by reason of its tail piece being struck by the shoulders 36as the web is being drawn. The web is inter osed between the feed rolls31 and 32, w lich latter is mounted on the shaft 41 in order thatit maybe positively driven. The shafts of the rolls 31 and 32 and the tapperare geared together so that they operate positive in unison, and aspower is imparted to t e drive shaft 56, the frame, through the,connections described, will be oscillated and as the frame isoscillated, the dog 43 will impart motion to the web to project afinished card beyond the knives, it being understood that the card willhave reached the limit of its outward movement at the time the movable.knife is approaching the stationary knife, this timing of the feed andthe movement of the cutting mechanism being one that will be understoodby those skilled in the art.

After the card is severed from the 'web in its coated state, it issubjected to a bak ing process through the em 10 mentof a conveyer andan oven, w ic conveyer should be located in such relation to ,the cuttindevice as to receive cards which drop rom the web as they are severed.

The conveyer and baking device or oven of the present invention includesany suitable frame 63 having drums 64 and 65 journaled at its ends, overwhich a wire mesh conveyer belt 66 is operated. It has been found inpractice that owing to the character of the wire mesh, the belt does notrun straight at all times, but has a tendency cased, but whichpreferably has a structure comprising a lurality of side posts 69 andupper and ower transversely disposed plates 70 and 71, respectively,that constitute supports or anchorages for the top and bottom walls 72and 7 3, respectively. The top and bottom walls may be of any heatresisting or refractory. material such as asbestos and they constitutebases on which the heating elements are installed.

belt 0 erates' through an oven which may be suita 1y en- It has beenfound in practice that the degree of heat effective to produce the bestresults in fusing, melting or' otherwise'treating the deposits used inembossed printingis a t to scorch the card when subjected to the mat forthe desired length of time to produce the best results, and therefore,the

applicant has providedan oven having zones o and 73 constitute bases onwhich appropriate fittings orlterminal plates 74 may be secured the samebeing arranged as separate units on each side of the bases and havingsuitable terminals to which resistance elements 7 5,-in the nature ofvire, may be connected in a manner to permit current to be supplied tothe group of resistance elements at one end of'the furnace, or to thegroup at the other and of the furnace, or to the groups simultaneously.Furthermore, each resistance element is a unit of comparatively shortlength extending from one plate to-the other, and if any one of theshort lengths becomes'impaired, it can be renewed without excessivecost.

The wiring diagram is shown in Fig. 6 and a description of the same isbelieved to be unnecessary to an understanding of the arrangement, itbeing sufficient to say that suitable switches 76are provided forcontrolling the circuits.

As the upper and lower walls of the furnace carry heating units, thecards will be subjected to heat from above and beneath and such heatingalso adds to the efficiency of an oven intended to treat deposits forembossed printing. but in order to maintain the conveyer in suchrelation to the heating devices as will cause a uniform action on thecards, the conveyer is guided within the furnace on cross-bars 77- whichare somewhat similar to the cross plates 70 and 71, except that thecross bars have convex upper surfaces to minimize the friction betweenthe conveyer belt and the said bars. Preferably the space between theconveyer and the upper heating elements is slightly greater than thedistance between the conveyer and the lower heating elements, as thiswill allow for any distortion of the card or material as it is beingcarried by the conveyer. When cards and the like are heated, they have atendency to .curl or bend, so that by the relation of parts justindicated, a greater clearance will be above the conveyer in order thateven if they become distorted, they will not come in contact with theheating elements. The presence of the lower heating element minimizesthe curlin action or distortionof the cards in order t at'if the heat isproperly regulated, there is little danger of undue misshaping of thecards.

Power may be applied for operating the drums in any convenient manner,but as here shown, a. shaft 78 has ,a pulley 79 secured on it, which maybe engaged b a belt or other driving means, the said s aft '78 having apinion 80 engaging a gear wheel 81 on a stub shaft 82. The gear wheel.81 is connected to a pinion 83 on the stub shaft for the purpose ofdriving the same, and the pinion .83 meshes with a gear wheel 84 on theshaft 85 of the drum '65. Of course, other means may be provided foroperating the conveyer, and the inventor does not wish to be limitedwith respect to the same.

It is the purpose of the inventor to have the arrangement such that hisswitches will deliver current to the heating agents in a manner toproduce heat at the upper and lower zones of the furnace at high and lowtemperatures or when the heat is increased or diminished and, of course,in the event that other heating a encies are employed, he would providefor heating both the upper and lower zones at about or approximately thesame temperature in order that the heat through which the web is movedfor r'eceiv-' prlate engths from the web.
